RFC 7600 IPv4 Residual Deployment via IPv6 - A Stateless Solution (4rd)
 
Authors:R. Despres, S. Jiang, Ed., R. Penno, Y. Lee, G. Chen, M. Chen.
Date:July 2015
Formats:txt pdf
Status:EXPERIMENTAL
DOI:10.17487/RFC 7600
This document specifies a stateless solution for service providers to progressively deploy IPv6-only network domains while still offeringIPv4 service to customers. The solution's distinctive properties are that TCP/UDP IPv4 packets are valid TCP/UDP IPv6 packets during domain traversal and that IPv4 fragmentation rules are fully preserved end to end. Each customer can be assigned one public IPv4 address, several public IPv4 addresses, or a shared address with a restricted port set.
 
RFC 7601 Message Header Field for Indicating Message Authentication Status

Date:August 2015
Formats:txt pdf
Status:PROPOSED STANDARD
DOI:10.17487/RFC 7603
The objective of Energy Management (EMAN) is to provide an energy management framework for networked devices. This document presents the applicability of the EMAN information model in a variety of scenarios with cases and target devices. These use cases are useful for identifying requirements for the framework and MIBs. Further, we describe the relationship of the EMAN framework to other relevant energy monitoring standards and architectures.
 
RFC 7604 Comparison of Different NAT Traversal Techniques for Media Controlled by the Real-Time Streaming Protocol (RTSP)
 
Authors:M. Westerlund, T. Zeng.
Date:September 2015
Formats:txt pdf
Status:INFORMATIONAL
DOI:10.17487/RFC 7604
This document describes several Network Address Translator (NAT) traversal techniques that were considered to be used for establishing the RTP media flows controlled by the Real-Time Streaming Protocol(RTSP). Each technique includes a description of how it would be used, the security implications of using it, and any other deployment considerations it has. There are also discussions on how NAT traversal techniques relate to firewalls and how each technique can be applied in different use cases. These findings were used when selecting the NAT traversal for RTSP 2.0, which is specified in a separate document.

RFC 7606 Revised Error Handling for BGP UPDATE Messages
 
Authors:E. Chen, Ed., J. Scudder, Ed., P. Mohapatra, K. Patel.
Date:August 2015
Formats:txt pdf
Updates:RFC 1997, RFC 4271, RFC 4360, RFC 4456, RFC 4760, RFC 5543, RFC 5701, RFC 6368
Status:PROPOSED STANDARD
DOI:10.17487/RFC 7606
According to the base BGP specification, a BGP speaker that receives an UPDATE message containing a malformed attribute is required to reset the session over which the offending attribute was received.This behavior is undesirable because a session reset would impact not only routes with the offending attribute but also other valid routes exchanged over the session. This document partially revises the error handling for UPDATE messages and provides guidelines for the authors of documents defining new attributes. Finally, it revises the error handling procedures for a number of existing attributes.

This document updates error handling for RFCs 1997, 4271, 4360, 4456,4760, 5543, 5701, and 6368.

 
RFC 7607 Codification of AS 0 Processing
 
Authors:W. Kumari, R. Bush, H. Schiller, K. Patel.

RFC 7608 IPv6 Prefix Length Recommendation for Forwarding
 
Authors:M. Boucadair, A. Petrescu, F. Baker.
Date:July 2015
Formats:txt pdf
Also:BCP 0198
Status:BEST CURRENT PRACTICE
DOI:10.17487/RFC 7608
IPv6 prefix length, as in IPv4, is a parameter conveyed and used inIPv6 routing and forwarding processes in accordance with theClassless Inter-domain Routing (CIDR) architecture. The length of anIPv6 prefix may be any number from zero to 128, although subnets using stateless address autoconfiguration (SLAAC) for address allocation conventionally use a /64 prefix. Hardware and software implementations of routing and forwarding should therefore impose no rules on prefix length, but implement longest-match-first on prefixes of any valid length.
 
RFC 7609 IBM's Shared Memory Communications over RDMA (SMC-R) Protocol
 
Authors:M. Fox, C. Kassimis, J. Stevens.
Date:August 2015
Formats:txt pdf
Status:INFORMATIONAL
DOI:10.17487/RFC 7609
This document describes IBM's Shared Memory Communications over RDMA(SMC-R) protocol. This protocol provides Remote Direct Memory Access(RDMA) communications to TCP endpoints in a manner that is transparent to socket applications. It further provides for dynamic discovery of partner RDMA capabilities and dynamic setup of RDMA connections, as well as transparent high availability and load balancing when redundant RDMA network paths are available. It maintains many of the traditional TCP/IP qualities of service such as filtering that enterprise users demand, as well as TCP socket semantics such as urgent data.
 
RFC 7610 DHCPv6-Shield: Protecting against Rogue DHCPv6 Servers
 
Authors:F. Gont, W. Liu, G. Van de Velde.
Date:August 2015
Formats:txt pdf
Also:BCP 0199
Status:BEST CURRENT PRACTICE
DOI:10.17487/RFC 7610
This document specifies a mechanism for protecting hosts connected to a switched network against rogue DHCPv6 servers. It is based onDHCPv6 packet filtering at the layer 2 device at which the packets are received. A similar mechanism has been widely deployed in IPv4 networks ('DHCP snooping'); hence, it is desirable that similar functionality be provided for IPv6 networks. This document specifies a Best Current Practice for the implementation of DHCPv6-Shield.
 
RFC 7611 BGP ACCEPT_OWN Community Attribute
 
Authors:J. Uttaro, P. Mohapatra, D. Smith, R. Raszuk, J. Scudder.
Date:August 2015
Formats:txt pdf
Status:PROPOSED STANDARD
DOI:10.17487/RFC 7611
Under certain conditions, it is desirable for a Border GatewayProtocol (BGP) route reflector to be able to modify the Route Target(RT) list of a Virtual Private Network (VPN) route that the route reflector distributes, enabling the route reflector to control how a route originated within one VPN Routing and Forwarding table (VRF) is imported into other VRFs. This technique works effectively as long as the VRF that exports the route is not on the same Provider Edge(PE) router as the VRF(s) that imports the route. However, due to the constraints of BGP, it does not work if the two are on the samePE. This document describes a modification to BGP allowing this technique to work when the VRFs are on the same PE and to be used in a standard manner throughout an autonomous system.
 
RFC 7612 Lightweight Directory Access Protocol (LDAP): Schema for Printer Services

Formats:txt pdf
Obsoletes:RFC 4013
Status:PROPOSED STANDARD
DOI:10.17487/RFC 7613
This document describes updated methods for handling Unicode strings representing usernames and passwords. The previous approach was known as SASLprep (RFC 4013) and was based on stringprep (RFC 3454).The methods specified in this document provide a more sustainable approach to the handling of internationalized usernames and passwords. The preparation, enforcement, and comparison of internationalized strings (PRECIS) framework, RFC 7564, obsoletes RFC3454, and this document obsoletes RFC 4013.
 
RFC 7614 Explicit Subscriptions for the REFER Method
 
Authors:R. Sparks.
Date:August 2015
Formats:txt pdf
Status:PROPOSED STANDARD
DOI:10.17487/RFC 7614
The Session Initiation Protocol (SIP) REFER request, as defined byRFC 3515, triggers an implicit SIP-Specific Event Notification framework subscription. Conflating the start of the subscription with handling the REFER request makes negotiating SUBSCRIBE extensions impossible and complicates avoiding SIP dialog sharing.This document defines extensions to REFER that remove the implicit subscription and, if desired, replace it with an explicit one.

RFC 7618 Dynamic Allocation of Shared IPv4 Addresses
 
Authors:Y. Cui, Q. Sun, I. Farrer, Y. Lee, Q. Sun, M. Boucadair.
Date:August 2015
Formats:txt pdf
Status:PROPOSED STANDARD
DOI:10.17487/RFC 7618
This memo describes the dynamic allocation of shared IPv4 addresses to clients using DHCPv4. Address sharing allows a single IPv4 address to be allocated to multiple active clients simultaneously, with each client being differentiated by a unique set of transport- layer source port numbers. The necessary changes to existing DHCPv4 client and server behavior are described, and a new DHCPv4 option for provisioning clients with shared IPv4 addresses is included.

Due to the nature of IP address sharing, some limitations to its applicability are necessary. This memo describes these limitations and recommends suitable architectures and technologies where address sharing may be utilized.

 
RFC 7619 The NULL Authentication Method in the Internet Key Exchange Protocol Version 2 (IKEv2)
 
Authors:V. Smyslov, P. Wouters.
Date:August 2015
Formats:txt pdf
Updates:RFC 4301
Status:PROPOSED STANDARD
DOI:10.17487/RFC 7619
This document specifies the NULL Authentication method and theID_NULL Identification Payload ID Type for Internet Key ExchangeProtocol version 2 (IKEv2). This allows two IKE peers to establish single-side authenticated or mutual unauthenticated IKE sessions for those use cases where a peer is unwilling or unable to authenticate or identify itself. This ensures IKEv2 can be used for OpportunisticSecurity (also known as Opportunistic Encryption) to defend againstPervasive Monitoring attacks without the need to sacrifice anonymity.

RFC 7623 Provider Backbone Bridging Combined with Ethernet VPN (PBB-EVPN)
 
Authors:A. Sajassi, Ed., S. Salam, N. Bitar, A. Isaac, W. Henderickx.
Date:September 2015
Formats:txt pdf
Status:PROPOSED STANDARD
DOI:10.17487/RFC 7623
This document discusses how Ethernet Provider Backbone Bridging (PBB) can be combined with Ethernet VPN (EVPN) in order to reduce the number of BGP MAC Advertisement routes by aggregating Customer/ClientMAC (C-MAC) addresses via Provider Backbone MAC (B-MAC) address, provide client MAC address mobility using C-MAC aggregation, confine the scope of C-MAC learning to only active flows, offer per-site policies, and avoid C-MAC address flushing on topology changes. The combined solution is referred to as PBB-EVPN.
 
RFC 7624 Confidentiality in the Face of Pervasive Surveillance: A Threat Model and Problem Statement
 
Authors:R. Barnes, B. Schneier, C. Jennings, T. Hardie, B. Trammell, C. Huitema, D. Borkmann.
Date:August 2015
Formats:txt pdf
Status:INFORMATIONAL
DOI:10.17487/RFC 7624
Since the initial revelations of pervasive surveillance in 2013, several classes of attacks on Internet communications have been discovered. In this document, we develop a threat model that describes these attacks on Internet confidentiality. We assume an attacker that is interested in undetected, indiscriminate eavesdropping. The threat model is based on published, verified attacks.
 
RFC 7625 Architecture of an IP/MPLS Network with Hardened Pipes
 
Authors:J. T. Hao, P. Maheshwari, R. Huang, L. Andersson, M. Chen.
Date:August 2015
Formats:txt pdf
Status:INFORMATIONAL
DOI:10.17487/RFC 7625
This document describes an IP/MPLS network that has an infrastructure that can be separated into two or more strata. For the implementation described in this document, the infrastructure has been separated into two strata: one for the "Hard Pipes", called the"Hard Pipe Stratum", and one for the normal IP/MPLS traffic, called the "Normal IP/MPLS Stratum".

This document introduces the concept of a Hard Pipe -- an MPLS LabelSwitched Path (LSP) or a pseudowire (PW) with a bandwidth that is guaranteed and can neither be exceeded nor infringed upon.

The Hard Pipe stratum does not use statistical multiplexing; for theLSPs and PWs set up within this stratum, the bandwidth is guaranteed end to end.

The document does not specify any new protocol or procedures. It does explain how the MPLS standards implementation has been deployed and operated to meet the requirements from operators that offer traditional Virtual Leased Line (VLL) services.

 
RFC 7626 DNS Privacy Considerations
 
Authors:S. Bortzmeyer.
Date:August 2015
Formats:txt pdf
Status:INFORMATIONAL
DOI:10.17487/RFC 7626
This document describes the privacy issues associated with the use of the DNS by Internet users. It is intended to be an analysis of the present situation and does not prescribe solutions.
 
RFC 7627 Transport Layer Security (TLS) Session Hash and Extended Master Secret Extension
 
Authors:K. Bhargavan, Ed., A. Delignat-Lavaud, A. Pironti, A. Langley, M. Ray.
Date:September 2015
Formats:txt pdf
Updates:RFC 5246
Status:PROPOSED STANDARD
DOI:10.17487/RFC 7627
The Transport Layer Security (TLS) master secret is not cryptographically bound to important session parameters such as the server certificate. Consequently, it is possible for an active attacker to set up two sessions, one with a client and another with a server, such that the master secrets on the two sessions are the same. Thereafter, any mechanism that relies on the master secret for authentication, including session resumption, becomes vulnerable to a man-in-the-middle attack, where the attacker can simply forward messages back and forth between the client and server. This specification defines a TLS extension that contextually binds the master secret to a log of the full handshake that computes it, thus preventing such attacks.
 
RFC 7628 A Set of Simple Authentication and Security Layer (SASL) Mechanisms for OAuth
 
Authors:W. Mills, T. Showalter, H. Tschofenig.
Date:August 2015
Formats:txt pdf
Status:PROPOSED STANDARD
DOI:10.17487/RFC 7628
OAuth enables a third-party application to obtain limited access to a protected resource, either on behalf of a resource owner by orchestrating an approval interaction or by allowing the third-party application to obtain access on its own behalf.

This document defines how an application client uses credentials obtained via OAuth over the Simple Authentication and Security Layer(SASL) to access a protected resource at a resource server. Thereby, it enables schemes defined within the OAuth framework for non-HTTP- based application protocols.

Clients typically store the user's long-term credential. This does, however, lead to significant security vulnerabilities, for example, when such a credential leaks. A significant benefit of OAuth for usage in those clients is that the password is replaced by a shared secret with higher entropy, i.e., the token. Tokens typically provide limited access rights and can be managed and revoked separately from the user's long-term password.

 
RFC 7629 Flow-Binding Support for Mobile IP
 
Authors:S. Gundavelli, Ed., K. Leung, G. Tsirtsis, A. Petrescu.
Date:August 2015
Formats:txt pdf
Status:EXPERIMENTAL
DOI:10.17487/RFC 7629
This specification defines extensions to the Mobile IP protocol for allowing a mobile node with multiple interfaces to register a care-of address for each of its network interfaces and to simultaneously establish multiple IP tunnels with its home agent. This essentially allows the mobile node to utilize all the available network interfaces and build a higher aggregated logical pipe with its home agent for its home address traffic. Furthermore, these extensions also allow the mobile node and the home agent to negotiate IP traffic flow policies for binding individual flows with the registered care- of addresses.
 
RFC 7630 HMAC-SHA-2 Authentication Protocols in the User-based Security Model (USM) for SNMPv3
 
Authors:J. Merkle, Ed., M. Lochter.
Date:October 2015

RFC 7631 TLV Naming in the Mobile Ad Hoc Network (MANET) Generalized Packet/Message Format
 
Authors:C. Dearlove, T. Clausen.
Date:September 2015
Formats:txt pdf
Updates:RFC 5444
Updated by:RFC 7722
Status:PROPOSED STANDARD
DOI:10.17487/RFC 7631
This document reorganizes the naming of already-allocated TLV (type- length-value) types and type extensions in the "Mobile Ad hoc NETwork(MANET) Parameters" registries defined by RFC 5444 to use names appropriately. It has no consequences in terms of any protocol implementation.

This document also updates the Expert Review guidelines in RFC 5444, so as to establish a policy for consistent naming of future TLV type and type extension allocations. It makes no other changes toRFC 5444.

 
RFC 7632 Endpoint Security Posture Assessment: Enterprise Use Cases
 
Authors:D. Waltermire, D. Harrington.
Date:September 2015
Formats:txt pdf
Status:INFORMATIONAL
DOI:10.17487/RFC 7632
This memo documents a sampling of use cases for securely aggregating configuration and operational data and evaluating that data to determine an organization's security posture. From these operational use cases, we can derive common functional capabilities and requirements to guide development of vendor-neutral, interoperable standards for aggregating and evaluating data relevant to security posture.
 
RFC 7633 X.509v3 Transport Layer Security (TLS) Feature Extension
 
Authors:P. Hallam-Baker.
Date:October 2015
Formats:txt pdf
Status:PROPOSED STANDARD
DOI:10.17487/RFC 7633
The purpose of the TLS feature extension is to prevent downgrade attacks that are not otherwise prevented by the TLS protocol. In particular, the TLS feature extension may be used to mandate support for revocation checking features in the TLS protocol such as OnlineCertificate Status Protocol (OCSP) stapling. Informing clients that an OCSP status response will always be stapled permits an immediate failure in the case that the response is not stapled. This in turn prevents a denial-of-service attack that might otherwise be possible.
 
RFC 7634 ChaCha20, Poly1305, and Their Use in the Internet Key Exchange Protocol (IKE) and IPsec
 
Authors:Y. Nir.
Date:August 2015

RFC 7637 NVGRE: Network Virtualization Using Generic Routing Encapsulation
 
Authors:P. Garg, Ed., Y. Wang, Ed..
Date:September 2015
Formats:txt pdf
Status:INFORMATIONAL
DOI:10.17487/RFC 7637
This document describes the usage of the Generic RoutingEncapsulation (GRE) header for Network Virtualization (NVGRE) in multi-tenant data centers. Network Virtualization decouples virtual networks and addresses from physical network infrastructure, providing isolation and concurrency between multiple virtual networks on the same physical network infrastructure. This document also introduces a Network Virtualization framework to illustrate the use cases, but the focus is on specifying the data-plane aspect of NVGRE.
 
RFC 7638 JSON Web Key (JWK) Thumbprint
 
Authors:M. Jones, N. Sakimura.
Date:September 2015
Formats:txt pdf
Status:PROPOSED STANDARD
DOI:10.17487/RFC 7638
This specification defines a method for computing a hash value over aJSON Web Key (JWK). It defines which fields in a JWK are used in the hash computation, the method of creating a canonical form for those fields, and how to convert the resulting Unicode string into a byte sequence to be hashed. The resulting hash value can be used for identifying or selecting the key represented by the JWK that is the subject of the thumbprint.

RFC 7641 Observing Resources in the Constrained Application Protocol (CoAP)
 
Authors:K. Hartke.
Date:September 2015
Formats:txt pdf
Status:PROPOSED STANDARD
DOI:10.17487/RFC 7641
The Constrained Application Protocol (CoAP) is a RESTful application protocol for constrained nodes and networks. The state of a resource on a CoAP server can change over time. This document specifies a simple protocol extension for CoAP that enables CoAP clients to"observe" resources, i.e., to retrieve a representation of a resource and keep this representation updated by the server over a period of time. The protocol follows a best-effort approach for sending new representations to clients and provides eventual consistency between the state observed by each client and the actual resource state at the server.

The System for Cross-domain Identity Management (SCIM) specifications are designed to make identity management in cloud-based applications and services easier. The specification suite builds upon experience with existing schemas and deployments, placing specific emphasis on simplicity of development and integration, while applying existing authentication, authorization, and privacy models. Its intent is to reduce the cost and complexity of user management operations by providing a common user schema and extension model as well as binding documents to provide patterns for exchanging this schema using HTTP.

This document provides a platform-neutral schema and extension model for representing users and groups and other resource types in JSON format. This schema is intended for exchange and use with cloud service providers.

Updates:RFC 6887
Status:PROPOSED STANDARD
DOI:10.17487/RFC 7652
An IPv4 or IPv6 host can use the Port Control Protocol (PCP) to flexibly manage the IP address-mapping and port-mapping information on Network Address Translators (NATs) or firewalls to facilitate communication with remote hosts. However, the uncontrolled generation or deletion of IP address mappings on such network devices may cause security risks and should be avoided. In some cases, the client may need to prove that it is authorized to modify, create, or delete PCP mappings. This document describes an in-band authentication mechanism for PCP that can be used in those cases.The Extensible Authentication Protocol (EAP) is used to perform authentication between PCP devices.

This document updates RFC 6887.

RFC 7657 Differentiated Services (Diffserv) and Real-Time Communication
 
Authors:D. Black, Ed., P. Jones.
Date:November 2015
Formats:txt pdf
Status:INFORMATIONAL
DOI:10.17487/RFC 7657
This memo describes the interaction between Differentiated Services(Diffserv) network quality-of-service (QoS) functionality and real- time network communication, including communication based on theReal-time Transport Protocol (RTP). Diffserv is based on network nodes applying different forwarding treatments to packets whose IP headers are marked with different Diffserv Codepoints (DSCPs).WebRTC applications, as well as some conferencing applications, have begun using the Session Description Protocol (SDP) bundle negotiation mechanism to send multiple traffic streams with different QoS requirements using the same network 5-tuple. The results of using multiple DSCPs to obtain different QoS treatments within a single network 5-tuple have transport protocol interactions, particularly with congestion control functionality (e.g., reordering). In addition, DSCP markings may be changed or removed between the traffic source and destination. This memo covers the implications of theseDiffserv aspects for real-time network communication, includingWebRTC.

RFC 7660 Diameter Congestion and Filter Attributes
 
Authors:L. Bertz, S. Manning, B. Hirschman.
Date:October 2015
Formats:txt pdf
Status:PROPOSED STANDARD
DOI:10.17487/RFC 7660
This document defines optional Diameter attributes that can be used to help manage networks that use Explicit Congestion Notification(ECN) or Diameter traffic filters. These new attributes allow for improved data traffic identification, support of ECN, and minimalDiameter filter administration.

RFC 5777 defines a Filter-Rule Attribute Value Pair (AVP) that accommodates extensions for classification, conditions, and actions.It, however, does not support traffic identification for packets using Explicit Congestion Notification as defined in RFC 3168 and does not provide specific actions when the flow(s) described by theFilter-Rule are congested.

Further, a Filter-Rule can describe multiple flows but not the exact number of flows. Flow count and other associated data (e.g., packets) are not captured by accounting applications, leaving administrators without useful information regarding the effectiveness or appropriateness of the filter definition.

The optional attributes defined in this document are forward and backwards compatible with RFC 5777.

 
RFC 7661 Updating TCP to Support Rate-Limited Traffic

Date:October 2015
Formats:txt pdf
Obsoletes:RFC 2861
Status:EXPERIMENTAL
DOI:10.17487/RFC 7661
This document provides a mechanism to address issues that arise whenTCP is used for traffic that exhibits periods where the sending rate is limited by the application rather than the congestion window. It provides an experimental update to TCP that allows a TCP sender to restart quickly following a rate-limited interval. This method is expected to benefit applications that send rate-limited traffic usingTCP while also providing an appropriate response if congestion is experienced.

This document also evaluates the Experimental specification of TCPCongestion Window Validation (CWV) defined in RFC 2861 and concludes that RFC 2861 sought to address important issues but failed to deliver a widely used solution. This document therefore reclassifies the status of RFC 2861 from Experimental to Historic. This document obsoletes RFC 2861.

The Strengthening the Internet (STRINT) workshop assembled one hundred participants in London for two days in early 2014 to discuss how the technical community, and in particular the IETF and the W3C, should react to Pervasive Monitoring and more generally how to strengthen the Internet in the face of such attacks. The discussions covered issues of terminology, the role of user interfaces, classes of mitigation, some specific use cases, transition strategies(including opportunistic encryption), and more. The workshop ended with a few high-level recommendations, that it is believed could be implemented and could help strengthen the Internet. This is the report of that workshop.

RFC 7688 GMPLS OSPF Enhancement for Signal and Network Element Compatibility for Wavelength Switched Optical Networks
 
Authors:Y. Lee, Ed., G. Bernstein, Ed..
Date:November 2015
Formats:txt pdf
Status:PROPOSED STANDARD
DOI:10.17487/RFC 7688
This document provides Generalized Multiprotocol Label Switching(GMPLS) Open Shortest Path First (OSPF) routing enhancements to support signal compatibility constraints associated with WavelengthSwitched Optical Network (WSON) elements. These routing enhancements are applicable in common optical or hybrid electro-optical networks where not all the optical signals in the network are compatible with all network elements participating in the network.

This compatibility constraint model is applicable to common optical or hybrid electro-optical systems such as optical-electronic-optical(OEO) switches, regenerators, and wavelength converters, since such systems can be limited to processing only certain types of WSON signals.

 
RFC 7689 Signaling Extensions for Wavelength Switched Optical Networks
 
Authors:G. Bernstein, Ed., S. Xu, Y. Lee, Ed., G. Martinelli, H. Harai.
Date:November 2015
Formats:txt pdf
Status:PROPOSED STANDARD
DOI:10.17487/RFC 7689
This document provides extensions to Generalized Multiprotocol LabelSwitching (GMPLS) signaling for control of Wavelength SwitchedOptical Networks (WSONs). Such extensions are applicable in WSONs under a number of conditions including: (a) when optional processing, such as regeneration, must be configured to occur at specific nodes along a path, (b) where equipment must be configured to accept an optical signal with specific attributes, or (c) where equipment must be configured to output an optical signal with specific attributes.This document provides mechanisms to support distributed wavelength assignment with a choice of distributed wavelength assignment algorithms.

Status:INFORMATIONAL
DOI:10.17487/RFC 7690
This document calls attention to the problem of delivering ICMPv6 type 2 "Packet Too Big" (PTB) messages to the intended destination(typically the server) in ECMP load-balanced or anycast network architectures. It discusses operational mitigations that can be employed to address this class of failures.
 
RFC 7691 Updating the Term Dates of IETF Administrative Oversight Committee (IAOC) Members
 
Authors:S. Bradner, Ed..
Date:November 2015
Formats:txt pdf
Updates:RFC 4071
Also:BCP 0101
Status:BEST CURRENT PRACTICE
DOI:10.17487/RFC 7691
BCP 101 defines the start and end dates for the terms of IETFAdministrative Oversight Committee (IAOC) members; these terms have proven to be impractical. This memo updates BCP 101 to direct theIAOC to establish more practical start and end dates for terms ofIAOC members.
 
RFC 7692 Compression Extensions for WebSocket
 
Authors:T. Yoshino.
Date:December 2015
Formats:txt pdf
Status:PROPOSED STANDARD
DOI:10.17487/RFC 7692
This document defines a framework for creating WebSocket extensions that add compression functionality to the WebSocket Protocol. An extension based on this framework compresses the payload data portion of WebSocket data messages on a per-message basis using parameters negotiated during the opening handshake. This framework provides a general method for applying a compression algorithm to the contents of WebSocket messages. Each compression algorithm has to be defined in a document defining the extension by specifying the parameter negotiation and the payload transformation algorithm in detail. This document also specifies one specific compression extension using theDEFLATE algorithm.
 
RFC 7693 The BLAKE2 Cryptographic Hash and Message Authentication Code (MAC)
 
Authors:M-J. Saarinen, Ed., J-P. Aumasson.
Date:November 2015
Formats:txt pdf
Status:INFORMATIONAL
DOI:10.17487/RFC 7693
This document describes the cryptographic hash function BLAKE2 and makes the algorithm specification and C source code conveniently available to the Internet community. BLAKE2 comes in two main flavors: BLAKE2b is optimized for 64-bit platforms and BLAKE2s for smaller architectures. BLAKE2 can be directly keyed, making it functionally equivalent to a Message Authentication Code (MAC).
 
RFC 7694 Hypertext Transfer Protocol (HTTP) Client-Initiated Content-Encoding
 
Authors:J. Reschke.
Date:November 2015
Formats:txt pdf
Status:PROPOSED STANDARD
DOI:10.17487/RFC 7694
In HTTP, content codings allow for payload encodings such as for compression or integrity checks. In particular, the "gzip" content coding is widely used for payload data sent in response messages.

Content codings can be used in request messages as well; however, discoverability is not on par with response messages. This document extends the HTTP "Accept-Encoding" header field for use in responses, to indicate the content codings that are supported in requests.

 
RFC 7695 Distributed Prefix Assignment Algorithm
 
Authors:P. Pfister, B. Paterson, J. Arkko.
Date:November 2015
Formats:txt pdf
Status:PROPOSED STANDARD
DOI:10.17487/RFC 7695
This document specifies a distributed algorithm for dividing a set of prefixes in a manner that allows for automatic assignment of sub- prefixes that are unique and non-overlapping. Used in conjunction with a protocol that provides flooding of information among a set of participating nodes, prefix configuration within a network may be automated.
 
RFC 7696 Guidelines for Cryptographic Algorithm Agility and Selecting Mandatory-to-Implement Algorithms
 
Authors:R. Housley.
Date:November 2015
Formats:txt pdf
Also:BCP 0201
Status:BEST CURRENT PRACTICE
DOI:10.17487/RFC 7696
Many IETF protocols use cryptographic algorithms to provide confidentiality, integrity, authentication, or digital signature.Communicating peers must support a common set of cryptographic algorithms for these mechanisms to work properly. This memo provides guidelines to ensure that protocols have the ability to migrate from one mandatory-to-implement algorithm suite to another over time.

RFC 7698 Framework and Requirements for GMPLS-Based Control of Flexi-Grid Dense Wavelength Division Multiplexing (DWDM) Networks
 
Authors:O. Gonzalez de Dios, Ed., R. Casellas, Ed., F. Zhang, X. Fu, D. Ceccarelli, I. Hussain.
Date:November 2015
Formats:txt pdf
Status:INFORMATIONAL
DOI:10.17487/RFC 7698
To allow efficient allocation of optical spectral bandwidth for systems that have high bit-rates, the International TelecommunicationUnion Telecommunication Standardization Sector (ITU-T) has extended its Recommendations G.694.1 and G.872 to include a new DenseWavelength Division Multiplexing (DWDM) grid by defining a set of nominal central frequencies, channel spacings, and the concept of the"frequency slot". In such an environment, a data-plane connection is switched based on allocated, variable-sized frequency ranges within the optical spectrum, creating what is known as a flexible grid(flexi-grid).

Given the specific characteristics of flexi-grid optical networks and their associated technology, this document defines a framework and the associated control-plane requirements for the application of the existing GMPLS architecture and control-plane protocols to the control of flexi-grid DWDM networks. The actual extensions to theGMPLS protocols will be defined in companion documents.

 
RFC 7699 Generalized Labels for the Flexi-Grid in Lambda Switch Capable (LSC) Label Switching Routers
 
Authors:A. Farrel, D. King, Y. Li, F. Zhang.
Date:November 2015
Formats:txt pdf
Updates:RFC 3471, RFC 6205
Status:PROPOSED STANDARD
DOI:10.17487/RFC 7699
GMPLS supports the description of optical switching by identifying entries in fixed lists of switchable wavelengths (called grids) through the encoding of lambda labels. Work within the ITU-T StudyGroup 15 has defined a finer-granularity grid, and the facility to flexibly select different widths of spectrum from the grid. This document defines a new GMPLS lambda label format to support this flexi-grid.

This document updates RFCs 3471 and 6205 by introducing a new label format.
